HOWARD C. WARFIELD, OF BROOKLYN, NEW YORK.

WINDOW-SCREEN.

Application filed .Tune 27, 1907.

To all whom 'it may concern:

Be it known that I, HOWARD C. WARFIELD, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Vindow-Screens; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in window screens.

The object of the invention is to provide a screen of this character constructed and arranged so as to permit the looking out of the window in any direction without removing the screen, and by means of which the flies and insects which may be on the inside of the screen can be readily turned out.

Vith this object in view, the invention consists of certain novel features of construction, combination and arrangement of parts as will be more fully described and particularly pointed out in the appended claims.

In the accompanying drawings, Figure 1 is a perspective view of a window showing the application of the screen thereto; Fig. 2 is an inner side view of the window screen, parts of the latter being broken away, and in section; Fig. 3 is a vertical sectional view; Fig. 4 is a horizontal sectional view g Fig. 5 is a detail vertical sectional view of a portion of one side of the screen frame, showing one of the notched blocks engaged with the fastening pin of the window frame; and Fig. 6 is a detail perspective view of one of the fastenin blocks.

eferring more particularly to the drawings, 1 denotes the screen frame which is adapted to fit within a window frame and the latter being preferably provided with strips, 2, arranged at each side of the screen frame, said strips being suitably fastened to the inner sides of the window frame, as shown. On the strips 2 are upper and lower inwardly projecting screen supporting pins or bolts 3, the inner end of which is preferably provided with a head, 4.

Ada ted to be set into the opposite sides of the ars of the screen frame are fastening or supporting blocks, 5, said blocks being provided with upwardly inclined slots or notches, 6. To the upper walls of the notches 6 are fixed curved securing springs, 7, the inner ends of which are bent to form a Specification of Letters Patent.

seat 8. Vhen the screen frame is inserted in a window, the notches 6 are engaged with the pins or bolts 3, which, when the screen is in place, are disposed in the upper ends of the notches 6, and in engagement with the seats 8 of the springs 7, the curved portion of which prevents the casual displacement or removal of the screen frame.

To the outer sides of the screen frame 1, adjacent to the upper and lower ends, are secured outwardly projecting curved or bowed screen supporting rods 9, around which is secured a wire netting screen 10, the inner edges of which are tacked or otherwise suitably secured to the side strips of the screen frame, as shown, said edges being preferably covered by a binding strip 12. The inner ends of the rods 9 are secured to the screen' frame by brackets 9, on which are formed sockets, through which the ends of the rods are passed. To the upper rod 9 is secured a semi-circular piece of netting 13, which forms the top of the screen. The inner edge of said netting is secured to the upper cross piece of the screen frame, said edge being covered by a binding strip 14. Secured to the lower rod 9 is a semi-circular piece of netting 15, which forms the bottom of the screen, and is covered by a binding strip 16. Over the meeting edges of the side, top and bottom ieces of the screen where the same joins or 1s connected to the su porting rods 9, are preferably secured binding strips, 17.

In applying the screen to a window, it is simply necessary to engage the lower ends of the notches 6 of the fastening blocks 5 with the supporting bolts 8 and to force the screen downwardly until said bolts are engaged with the upper ends of the notches and rest in the seats of the securing springs 7. In removing the screen from a window, it is simply necessary to push the same upwardly until the supporting pins or bolts 3 are opposite the lower open ends of the notches 6, after which the screen may be readily pushed outwardly and disengaged from the supporting pins.

I-Iaving described my invention, what I claim as new, and desire to secure by Letters- Patent, is:

1. A window screen comprising a frame, a semi-cylindrical screen secured to the outer side of said frame, and projecting outwardly beyond the window, upper and lower fastening blocks inserted in the side ieces of the screen frame and having forme( therein upwardly inclined notches, strips arranged on the inner sides of the window frame, and headed fastening pins secured to said strips and adapted to be engaged by said notched fastening blocks to detachably secure the screen in place, substantially asdescribed.

2. A window screen comprising a frame,

upper and lower curved or bowed screen supporting rods secured at their inner ends to said screen frame, wire netting to bottom and sides secured to said rods an frame to form a semi cylindrical screen, fastening blocks secured to the inner side of the screen frame, said blocks having formed therein upwardly inclined notches, supporting bolts or pins arranged in the sides of the window frame and adapted to be engaged by said notched blocks to support the screen in place, and means to prevent the casual disengagement of the screen from said pins or bolts, substantially as described.

3. A window screen comprising a frame, upper and lower curved or bowed screen-supporting rods secured at their inner ends to said screen frame, wire netting to bottom and sides lsecured to said rods an frame to form a semicylindrical screen, fastening blocks secured to the inner side of the screen frame, said blocks having formed therein upwardly inclined notches, supporting blocks or pins arranged in the sides of the window vand sides secured to said rods and frame to form a semi cylindrical screen, fastening blocks secured to the inner side of the screen frame, said blocks having formed therein upwardly inclined notches, strips arranged on the inner side of the window frame, headed supporting pins or bolts arranged in said strips and adapted to be engaged by said notched blocks to hold the screen in place, and curved springs arranged in said notches to engage said ins or bolts and thereby prevent the casualpdisengagement of the screen frame, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses. Y
